IM PROVEM ENT IN COLTERS.

Specification forming part of Letters Patent No. 220,161, dated September 30, 1879 g application filed June 19, 1879.

To all 'whomit may concern:

Be it known that I, KiNvoN W. MANWAR- ING, of Moline, in 'the' county of Rock Island and State of Illinois, have invented a new and useful Improvement in Plow-Uolters, ot` which the following is a specification.

This invention relates to improvements in plow-colters employed to open the surface of the ground in advance ot' the plow.

The object of this invention is to produce an improved device by which plow-colters, whether rolling or rigid, may be fixed to the beams of plows, whether right or let't hand, and by means of which the colter may be readily adjusted vertically to regulate their working depth, and laterally to properly line them with the plow.

4To this end I have invented and constructed the device represented in the accompanying drawings, in which- Figure l is a side eleva-tion 0f my improvement with colter attached, and as applied to the plow-beam, of which Fig. 2 is a rea-r view, in which the plow-beam is shown in section cut on dotted line x. Fig. 3 is an elevation ofthe side applied to the beam. Fig. 4 is a plan or top view. Fig. 5 is a transverse section on dotted line x', and Fig. 6 is a vertical central section on dotted lines x and x. Fig. 7 is a side elevation of the same device,

in which a colter-shank of rectangular-bar form is employed instead of the round-bar shank shown in the ligures from 1 to 6, inclusive. Fig. 8 is a plan or top view of Fig. 7. Fig. 9 is a side elevation ot a modified form of my improved device, of which Fig. 10 is a plan view. Fig. ll is an isometrical representation of a knife-colter.

In the ligures, A represents a clamp-trame, composed of plates c and ci', of the form represented in the drawings, and are ot' proper size to receive the plow-beam. These plates are placed some distance from each other, being connected near their centers by crossbars b, which form a crosswise opening between them of slot form, sufficiently large to receive the shank of the screw-eyebolt c, to permit it to be moved lengthwise of the slot freely. The plates a and a are also connected toward their ends by other crosswise bars, d, having their outer-face edges corrugated;

and the plates a and a are provided with holes e near their'outer ends, and are adapted to receive the screw-threaded ends ofthe screwstaple j'. These plates a and c', with the crosswise bars b and d, form the main clamp-frame ot' my improvement.

The outer face of the plate a', which comes in contact with the plow-beam, is corrugated, for the purpose ot' increasing its hold on the beam when clamped thereto.

B represents an adjustable bolster, composed of the curved bar g, provided with a central opening to receive the shank of the 'screw-eyebolt c, and with end plates, 7L, one edge of which is corrugated to receive the corrugations of the crosswise end bars, d, and their outer edges are of concave form to receive the vertical shank ot the colter.

t' is the vertical shank of the colter, which, in this instance, is of round-barform. c is an eyebolt with screw-threaded shank.

The vertical shank of the colter is passed through the eye of the eyebolt, and the screwthreaded shank of the eyebolt is passed through the center opening in the curved bar of the bolster, and through the center erosswise slot in the fra-me formed between the center crossbars thereof. In this position the vertical shank of the colter will rest in the concave outer edges of the bolster ends, and the corrugations of the' bolster will engage the corrugations of crosswise bars ot' the frame; and by means of the screw-nut l the parts, when adjusted, can be firmly held in position.

The lower end ot' the vertical shank ot' the colter is of journal form, adapted to receive the yoke m, which is swiveled thereto, and limited in its vibratory movements by means ot' the pin a and slot 0, in the usual manner.

Thel yoke m is formed of two curved arms, between the outer ends of which the colter C is journaled, in a manner substantially the same as is common in such work.

D represents a portion ot' a plow-beam with my improved device fixed in position thereon by means of the screw staple-bolts f.

From the foregoing it will be seen that the vertical shank 'i of the colter, and consequently the colter thereto attached, is made verticallyrv adjustable, to regulate the working depth of the colter, by means of its eyebolt-connection with the clamping-frame, which is accomplished by loosening the screw-nut l and sliding the shank up or down, and when adjusted by tightening the screw-nut it will be held firmly in its adjusted position; and in connection with the screw-eyebolt, the corrugated surfaces ot' the bolster and of the crosswise bars of the frame, and the crosswise slotted center of the frame, the colter is made laterally adjustable to place it properly in line with the plow.

This device is capable of use on either side of the plow-beam, and consequently equally applicable oli either right or left hand plows. This is accomplished by inverting the frame.

In Figs. 7 and 8, E represents the vertical shank of the colter, which, in this instance, is of rectangular-bar form. In the use of this form of coltershank it will require the eyebolt to be iliade of corresponding rectan gular form, as shown at p, to receive the shank E, and the outer edges of the end plates, h, of the bolster B will require to be notched to receive the edge of the colter-shank. This form is also adapted to the use ot the rigid knifeformed colter represented at Fig. 11, and their vertical and lateral adjustments are the same, and accomplished in the same manner as the adjustments of the round shank hereinbefore described.

In Figs. 9 and 10 I have represented a modilication of my improvement, in which I have employed the tubular socket F instead of the holsters employed in the previously-described forms. This tubular socket is made laterally adjustable in the same manner as the holsters in the previous forms, and is held in position on the clamp-frame by a suitable screw-bolt, r, passed through the socket from its front side in an opening prepared to receive it, and by means of the screw-nut t is iirmly secured to the clamp-frame. This tubnlarsocket receives the journal-formed eolter-shank H, which is held in position in the socket by a pin passing through its upper end above the socket, which,

in connection with the notched upper end of the socket, serves to limit the vibratory movement of the colter attached to the lower end of the journal-formed colter-shank.

s are rosette heads, fitted to the lower end of the shank H, having their outer faces radially corrugated to receive similar corrugated rosette-heads s', having their outer faces grooved to receive the upper ends of the yoke-arms u. These parts are firmly held in place by a screwbolt, which is passed through the parts in the center of the rosettes. The colter C is jour naled in the outer ends of the yoke-arms in the usual manner.

By this construction it will be seen that it' the clamping-bolt which passes through the parts in the center of the rosettes be loosened, the yoke-arms and the colter thereto attached may be raised or lowered, to regulate the working depth of the colter, and, when adjusted, can be fixed in position by tightening the screw-bolt.

I claim as my invention- 1. The combination, with the clampframe, substantially as herein described, of the bolster, the colter-shank, and the screw-eyebolt, these parts constructed and operating to hold the colter in an adjustable manner vertically, to regulate its working depth, and capable of use on right and left hand plows, substantially as and for the purpose hereinbefore set forth.

2. The combination of the laterally-slotted clamp-frame, the bolster, the screw-eyebolt, and colter-shank, constructed and operating as herein described, to adjust the colter both up and down and sidewise, and capable of use on both right and left hand plows, substantially as and for the purpose hereinbefore set forth.
